Answer:
true false true
Step-by-step explanation:
Answer:
AB= 12.94ft, 108deg
ZY= 6.76ft 50deg
XY 3.05ft, 22deg
Pathway adds up to 22.95ft
Step-by-step explanation:
AB is base
Sides 8 feet each = isosceles. =8ft, 8ft, 12.94ft
Top angle is 36 degree = 36°.36°,108°
ZY is base
Sides 8 feet each = isosceles = 8ft, 8ft, 6.76ft
Top angle is 65° = 65° 65° 50 °
XY is base
Sides 8 feet each =isosceles =8ft, 8ft, 3.05ft
Top angle is 79° degree = 79°,79 °,22 °
Pathway means triangles in a row side by side = Product of 3 values = ? feet
12.94 +6.76 + 3.05 =22.95ft pathway

Answer:
Step-by-step explanation:
Given that the time to complete a standardized exam is approximately normal with a mean of 70 minutes and a standard deviation of 10 minutes.
P(completing exam before 1 hour)
= P(less than an hour) = P(X<60)
=P(Z<
)
=0.5-0.34=0.16
i.e. 16% of students completed the standardized exam.
